The shortest story in the anthology, it strives for wry humor in how non-scientists think about science. Our underwhelming hero builds a gravity wave detector out of green gelatin in his bathtub and learns that our universe is doomed. There is more than a whiff of condescension, undoing the effort at humor.
“Message Found in a Gravity Wave” by Rudy Rucker, originally published in Nature.
